+\subsection options_modelchecking_visited model-check/visited, Cycle detection
+
+In order to detect cycles, the model-checker needs to check if a new explored
+state is in fact the same state than a previous one. In order to do this,
+the model-checker can take a snapshot of each visited state: this snapshot is
+then used to compare it with subsequent states in the exploration graph.
+
+The \b model-check/visited is the maximum number of states which are stored in
+memory. If the maximum number of snapshotted state is reached some states will
+be removed from the memory and some cycles might be missed.
+
+By default, no state is snapshotted and cycles cannot be detected.
